Earnings Per Share [Abstract] |
Earnings Per Common Share | Earnings Per Common Share Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. The computation of diluted earnings per common share is similar to that of basic earnings per common share, except that the former reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock. Potentially dilutive securities include outstanding restricted stock units and performance-based restricted stock units. The computations for basic and diluted earnings per common share were as follows:
